Psilocybin, a psychedelic compound, has fast-acting antidepressant-like effects in mice. Using tests of hedonic behavior and a drug that blocks hallucinogenic 5-HT2A receptors, the results suggest that altered perception may not be required for its therapeutic benefits. Psilocybin also strengthens connections between brain cells in regions involved in reward and emotion processing. These findings indicate it may be possible to retain psilocybin's antidepressant actions while minimizing alterations in consciousness.
